IMPRQVEMENT IN MAKING BRAID.

Be it known that I, JOSEPH FLETCHER,'of the city and county of Providence, and State of Rhode Island,

have invented a-new and useful Improvement in Making Braid; and I do hereby declare the same to be fully described, as follows:

In manufacturing ordinary flat or round braid, such as is used for corset and other lacings, the yarns, (employed on the bobbins of the racers of the braiding-machine,) when single and twisted, have all had their twists running in one direction. The" consequence has been that the braid, when formed, would twist, and not,

lie flat. To obviate this difiiculty, it has been customary to employ double'strand yarns, that is, yarns com-- posed of two strands, so twisted and intertwisted, that when left to themselves, or unwound from the bobbin, there would be no untwisting of the strand. But this metlrodoi' forming the yarns of the braid is expensive, and therefore it has been very desirable to find some mode of making the braid oi" single-strand yarns, and this I have discovered. I

In carrying out my invention, I employ a single-strand yarn on each of the bobbins ofthe racers of the braiding-machine, but half or nearly half'the yarns I twist in one direction, and the rest I twist in the opposite direction; in'other words, half or nearly half the number of bobbins are to be mounted or supplied with yarns twisted in one direction only, and the rest of the bobbins should be mounted or provided with yarns twisted in the opposite direction. It is to be understood that the yarn so used would untwist itself were it drawn. 0d the bobbin, and left free to do so. v v

The order ol'arrangement of the bobbins 'charged with the twisted single-thread yarns is not very material, the object being to counteract the tendency of a portion of the yarns to twist the braid in one direction by the tendency of the remainder of them to twist it in the oppositedirectio i. In this way, single-strand braid may be made, with little or no tendency to twist .itself when completed. It can be so made much cheaper than the double-strand braid, for the reason that in the first place, we save the process and expense of doubling the strands to form the yarns, and, in the second place, wemake the single strand the same sizeas the double strand, and save one twisting, which would be necessary when two strands are requiredto th-eyarnr Furthermore, there is economy in the process in other respects. &

I claim my improved mode, substantially as herein described, of making braid by a braiding-machine, such involving the making it of single-strand yarns, and the arrangement of the twists of a. portion of them in directions opposite to those of the rest, the same being as and forthe purpose specified.

JOSEPH FLETCHER.
